Patented Feb. 2.7, 1940 1 claim. A(c1. :wr-.101)l This invention relates in general to pivoted joints and more particularly tohinges and the I method of making the same. The object of the invention is to provide, a

' 5 new and improved pivoted joint or hinge .which isk of simple I'and reliable construction and which may be easily and cheaplymanufactured.

A'feature of the invention relates to the construction of the pivoted joint or hinge and in l the mannerin which the separable members are pivotally secured. v v

The inventionis illustrated in the accompanying drawing in which Fig. 1 shows a plan view of the preferred pivoted joint or hinge, Fig. 2

Fig. 1, Fig. 3 shows an exploded view, Fig. 4 shows 'the cup-shaped bearing member and Fig.

shows a bearing hole cut in one of the separablel members.

Figs. 6, 7, 8 and 9 show cross-sections of different modications ofthe invention. j

Referring now to the preferred arrangement shown in Figs. 1 to 5, inclusive, the hinge comprises three members: the separable pivoted 2,5 members I 0 and Il and the bearing member I5.

The pivoted member I0 may be of any desired' shape and may consist of metal or any suitable rigid material.

'I'he other pivotal member yII may also be lof any desired shape but must consistv of some kind of fusible metal, preferably ferrousmetal. The

cup-shaped bearing member I5 should consist,

preferably, 0f the same fusible metal as member l I.

` A hole I3 is counter-sunk in member I0 as shown in Figs. 3 and 5. The cup-shapedy bearing member I5, shown in Figs. 3 and 4 hasra bearingl surface I4 extending around its periphery, an upper surface or edge I2, and a'lower surface y or bottom I8. This cup-shaped bearing member is preferably made from a flat sheet `of metal and is -punch-pressed in the form shown by a suitable die in a punch-press. The cup-shaped `bearin'g'member I5 has an overall depth equal to the thickness of the Amember III and. is 4inserted inthe hole I3 so that the bearingsurface I4 engages the beveled edge of hole I3. When the bearing member I5 is inserted inhole I3, the upper edge I2 is flush with the upper'face of 540 ymember Il) and the lower surface or bottom I6 of the bearing member is flush with the lower face ofl member I0. The member is now placed in desired position with its upper face adjacent the lower face of memberl I0 in whichA vII position the lower surface I6 of the bearing f shows a cross section taken on the line X--X-of member |5 is res/ting against the upper 4faceof. member i After this assembly the bottom or surface I6 of the bearing member is spot welded to member II as indicated at |9 thereby rigidly securing bearing member I5 to-member II. The 5 hole I3 and the bearing surface I4 of thebearing member are `of substantially the same diameter to enablev the two members I0. and II to easily pivot. Due to the slanting or beveled edges of hole I3 and bearing member I5, which is now 10 rigidly'` secured to member II by spot welding I9, the two members I 0 and II are pivotally secured to each other. Since the edge I2` of bearing member I5 is iiush with the face of member I0, there are no objectionable projections l5" `which extend therefrom to yinterfere with any movement of the pivcted joint in case the joint as a whole is to be movedan appreciable distance. The modification sho-wn in Fig. 6 comprises two bladesor arms 20 and 2|, similar to members ID 20 and of Figs. 1 and 3, and a cup-shaped Iflanged bearing member 25, somewhat similar to member I5. In this modification the member 29 is counl ter-bored as shown at 23 to provide the bearing surfacesffor the flangedperiphery of the cup- 25 y shaped` bearing member 25. AThe members 20, 2| and 25 are assembled and the bearing mem- '.-ber 25 iswelded to member 2| in the same manner as previously described.

The modification shown in Fig. 7 is a pivoted 30 joint orv hinge of a much larger type than those previously described. This hinge comprises two plates or rblades 30 and 3|, somewhat similar but larger than blades I0 and I I, and a bearing memf ber35 in the form of a vrace or collar-shaped ring 35 y having slanting edges of which the outer edge 34 acts as the bearing surface. The' bearing member 35 isinserted Iinv the beveled hole 33 with the edges 34 Aand 36 flush with the two surfaces of plate 30 and then welded, as shownat 39, to 40 the plate `3| to pivotally secure member 3|) to f member 3|. I l .Y

The modification shown in Fig. 8 is similar to Figs. 1 to 5 inclusive except that the bearing member is a solidor coined bearing member 45 l which is` welded to member 4| as shown at 49 to pivotallyA secure member '40 topmember 4I.

A further modification shown in Fig. 9 comprises two pivoted members 5|) and 5| each having a countersunk hole 53 and ltwo cup-shaped 50y bearing members 55 with their smaller surfaces orv bottoms 56 Welded together at 59. The two members and 5I are rotatable on the periphery bearing surfaces 54 of their associated bearing members 55. Due tothe slanting edges 54 of 55 the welded bearing members 55 and the beveled edges 53 of the holes, the members 50 and 5|' are pivotally secured together. In this modification only the two cup-shaped bearing members 55 need be of fusible metal while the pivoted is also no tendency to a sloppy or loose jointy when the bearing hole and bearing member are made to the proper dimensions. In addition the'Y V extending `projections or the enlarged portion at..

the joint itself has been done away with to en# able the joint as a wholeto be 'moved'. There# fore, projections adjacent the path ofv travel of v the joint do not interfere with the movementof' the joint.

-, gether y Having described the invention, what is considered new and is desired to have protected by Letters Patent will be set forth in the following claim.

What is claimed is: l Y A hinged joint for connecting the ends of two fiat strip like members having adjacent faces,

oneof said members having an aperture extending therethrough, the diameterof said aperture being greater on the outer face of -said one member than on the opposite adjacent face of said one member, a hollow plug member conforming in shape to the shape of said aperture and disin abutting relation with the adjacent face of the otherof. said two members, and a fused .metal` g connection rigidly securing the abutting surfaces of said plug member and said other member ton posed in said aperture with its inner end surface I jl
